Studien-Informationen

Detailed Description:

BRCA1/2 mutation carriers have a considerably increased risk to develop breast and ovarian

cancer during their lifetime. There is evidence from the literature that for sporadic breast

cancer disease risk and the course of disease can be significantly influenced by physical

activity, nutrition and weight. The hypothesis of this 3 year, prospective randomized

multicenter efficacy trial is that a structured life-style intervention program with exercise

training and mediterranean diet is effective regarding increased adherence to a mediterranean

diet, reduction of body mass index, and increase of physical fitness.

Ein-/Ausschlusskriterien

Inclusion Criteria:

- proven pathogenic BRCA1/2 mutation

- age >=18

- written informed consent

Exclusion Criteria:

- current chemotherapy of radiotherapy (inclusion 6 weeks after CTX or RX possible)

- metastatic tumor disease

- life expectancy <3 years

- clinically limiting cardiovascular or respiratory disease (instable CVD, heart failure

stage IV, COPD GOLD IV, maximum resting blood pressure 160/100 mmHg)

- significant orthopedic disability which prevents from participating in the group

interventions

- severe concomitant diseases which prevents from participating in the group

interventions

- Karnofsky index <60

- maximum exercise capacity <50 W

- food allergies which prevent from mediterranean diet

- vegan diet

- body mass index <15 kg/m2

- pregnancy

- insufficient knowledge of German language

- insufficient compliance

- active participation in other interventional trials

Studien-Arme

  • No Intervention: Control
    Study participants are instructed regarding a healthy diet according to the recommendations of the German Nutrition Society (DGE) and are informed about positive effects of physical activity on incidence and prognosis of breast cancer
  • Experimental: Intervention
    Structured exercise training plus mediterranean diet: Study participants receive a lifestyle intervention of 12 months duration (3 months intensive intervention plus 9 months maintenance using monthly contacts and meetings). The intervention comprises a structured intensified training based on the results of physical performance diagnostics and a nutrition program based on a mediterranean diet.

Geprüfte Regime

  • Structured exercise training plus mediterranean diet:
    Structured exercise training plus mediterranean diet
